Summary:                    module hangs at seemingly random times
Description: 
sometimes i start playing a song, and it starts playing a few second or so
and hangs, then i kill the application and modprobe -r all sound modules
and modprobe them again to make it work again.

BUT: sometimes not only that happens, but also when i try to kill the apps
it will not kill. when that happens, all kill, killall, top, ps aux
commands hang at the command line and cannot be killed by CTRL-C or
otherwise, i have been able to see that when i stopped my display
managener I did an lsmod and it gave something like this:

snd-pcm-oss            59752  11
snd-mixer-oss          20480  1 snd-pcm-oss
snd-au8810             43760  220
snd-ac97-codec         83408  1 snd-au8810
snd-pcm               108172  112 snd-pcm-oss,snd-au8810,snd-ac97-codec
snd-page-alloc         10384  1 snd-pcm
gameport                3840  1 snd-au8810
snd-mpu401-uart        11904  1 snd-au8810


as you can see the snd-au8810 module seem to have an impossible number of
"dependencies" (i think has to do with the number of unclosed sound-apps
trying to be played; this could be since gaim is programmed to execute an
'aplay %s')

i've had this major crash below only 3 times; and the logs didn't detect
anything specific at the time. the only thing the logs mentioned at that
time was an ntpd sync going on; so the only thing i can think of is that
at a certain moment when a sync is going on, some kind of lock is holding
cause this to happen... the only thing that i can do to fix this is
reset...

it is interesting to note that i also have an snd-emu10k1 as second card,
which never gave problems like this, and i am always able to "modprobe -r
snd-emu10k1" ...

i forgot to note that i have the mdk 10.1 x86_64 distro and my version has
a few 64bit fixes to get past kernel hangs and kernel oopses
